Description

Technical Field

[0001] This utility model relates to the field of adsorption reaction equipment technology, specifically to an adsorption reaction vessel with a self-cleaning discharge mechanism. Background Technology

[0002] Adsorption reactors can be used to process liquid materials containing powder particles. During the reaction, the material is typically stirred by a stirrer inside the shell to ensure full contact between the powder particles and the liquid. After processing, the material is discharged through a feed inlet located at the bottom of the shell. To control the discharge, a sealing structure that can be opened and closed is usually required at the feed inlet.

[0003] In the process of handling materials containing powder particles, the sealing structure located near the feed inlet will repeatedly come into contact with the material. With the increase of usage time, some powder particles tend to adhere to and accumulate on the surface of the sealing structure. As the amount of deposits gradually increases, it may increase the resistance during the movement of the sealing structure, affecting the normal opening and closing of the feed inlet; at the same time, particles remaining on the surface of the sealing structure may also enter between the sealing structure and the sealing part, affecting the fit effect in the closed state.

[0004] For the aforementioned deposits, frequent equipment shutdowns and manual cleaning of the discharge structure would increase equipment maintenance. Therefore, existing adsorption reactors still have room for improvement in reducing the continuous adhesion and accumulation of powder particles at the discharge sealing points and minimizing the impact of powder residue on discharge opening and closing and sealing. Utility Model Content

[0005] The purpose of this invention is to provide an adsorption reactor with a self-cleaning discharge mechanism to reduce the continuous adhesion and accumulation of powder particles at the discharge sealing part, and reduce the impact of powder residue on the discharge opening and closing and sealing coordination.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adsorption reactor with a self-cleaning discharge mechanism includes a motor and a filter assembly. The filter assembly includes a shell, a stirring element disposed inside the shell, and a feed inlet disposed at the bottom of the shell. The motor is drivenly connected to the stirring element.

[0007] The bottom of the filter assembly is provided with a discharge assembly, which has a discharge channel corresponding to the feed inlet and a guide groove. A sealing disc is slidably provided in the guide groove. The sealing disc can move along the guide groove between a closed position that blocks the feed inlet and a discharge position that avoids the feed inlet.

[0008] The discharge assembly is equipped with an opening and closing element, which is connected to the sealing disc and can drive the sealing disc to reciprocate along the guide groove. By moving the sealing disc between the closed position and the discharge position, the material inlet can be closed and opened.

[0009] The discharge assembly is equipped with a flexible scraper, which is located on the moving path of the sealing disc, and the scraping end of the flexible scraper is in elastic contact with the surface of the sealing disc. When the sealing disc moves along the guide groove, the sealing disc and the flexible scraper scrape against each other, so that the surface of the sealing disc can be scraped by the flexible scraper while performing the opening and closing action of the feed port.

[0010] Furthermore, the scraping end of the flexible scraper makes elastic contact with the side surface of the sealing disc facing the feed inlet. As the sealing disc reciprocates between the closed position and the discharge position, the flexible scraper scrapes the side surface of the sealing disc. This allows for cleaning of the side surface of the sealing disc corresponding to the feed inlet, reducing the continuous residue of powder particles on that surface.

[0011] Furthermore, the opening and closing element includes a threaded post and a limiting disc disposed at the end of the threaded post, the threaded post being threadedly engaged with the discharge assembly.

[0012] Furthermore, the limiting disc is rotatably connected to the sealing disc. When the threaded column rotates, it moves axially relative to the discharge assembly and pushes or pulls the sealing disc along the guide groove via the limiting disc. Since the limiting disc can rotate relative to the sealing disc, the axial displacement generated by the rotation of the threaded column can be transmitted to the sealing disc, causing the sealing disc to move linearly along the guide groove.

[0013] Furthermore, the discharge assembly is provided with a sealing ring, which is set corresponding to the feed port. When the sealing disc moves to the closed position, it fits with the sealing ring. The sealing effect of the feed port in the closed state is improved by the cooperation between the sealing disc and the sealing ring.

[0014] Furthermore, the discharge assembly is detachably connected to the filter assembly via fasteners. The fasteners are located at the connection point between the discharge assembly and the filter assembly. After removing the fasteners, the discharge assembly can be detached from the bottom of the filter assembly, so that the discharge assembly and its internal structure can be cleaned and repaired after long-term use of the equipment.

[0015] This invention features a flexible scraper that elastically contacts the surface of the sealing disc along its movement path. This allows the sealing disc to move relative to the scraper during the opening and closing of the feed inlet, thus utilizing the disc's own opening and closing motion to scrape its surface. This structure eliminates the need for a separate cleaning process, reducing the continuous adhesion and accumulation of powder particles on the surface of the sealing disc while simultaneously opening and closing the discharge port. This helps minimize the impact of deposits on the movement of the sealing disc and subsequent sealing operations.

[0016] Meanwhile, the threaded engagement between the threaded column and the discharge assembly enables axial movement, and the limiting disc, which is rotatably connected to the sealing disc, pushes or pulls the sealing disc, causing the sealing disc to move along the guide groove; the sealing ring engages with the sealing disc in the closed position, which helps to improve the sealing effect after the feed port is closed.

[0017] In addition, the discharge assembly is detachably connected to the filter assembly via fasteners. After long-term operation, the discharge assembly can be removed from the bottom of the filter assembly, which facilitates further cleaning, inspection and maintenance of the sealing disc, guide groove, flexible scraper and sealing ring area inside the discharge assembly.

[0020] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0021] like Figures 1 to 3As shown, this utility model provides an adsorption reactor with a self-cleaning discharge mechanism, including a motor 1, a filter assembly 2, and a discharge assembly 3 disposed at the bottom of the filter assembly 2. The filter assembly 2 includes a shell 21, a stirring element 22 disposed inside the shell 21, and a feed inlet 23 disposed at the bottom of the shell 21. The motor 1 is disposed on the upper part of the shell 21 and is drivenly connected to the stirring element 22. When the motor 1 is running, it can drive the stirring element 22 to rotate inside the shell 21 to stir the material entering the shell 21. After the material is processed, it can enter the discharge assembly 3 through the feed inlet 23 at the bottom of the shell 21 and be discharged outward by the discharge assembly 3.

[0022] like Figure 2 and Figure 3 As shown, the discharge assembly 3 is located at the bottom of the filter assembly 2. The discharge assembly 3 is provided with a discharge channel corresponding to the feed inlet 23, so that after the feed inlet 23 is opened, the material inside the housing 21 can enter the discharge channel of the discharge assembly 3 through the feed inlet 23.

[0023] The discharge assembly 3 is provided with a guide groove 32, and a sealing disc 33 is slidably disposed within the guide groove 32. The guide groove 32 extends along the moving direction of the sealing disc 33, guiding the movement of the sealing disc 33 and enabling the sealing disc 33 to reciprocate within the discharge assembly 3. The sealing disc 33 has a closed position and a discharge position. When the sealing disc 33 moves along the guide groove 32 to below the feed inlet 23, the sealing disc 33 is in the closed position and blocks the feed inlet 23; when the sealing disc 33 moves along the guide groove 32 from below the feed inlet 23 outward, so that the sealing disc 33 avoids the feed inlet 23, the sealing disc 33 is in the discharge position, at which time the feed inlet 23 is connected to the discharge channel of the discharge assembly 3.

[0024] Figure 2 The diagram illustrates the fit between the discharge assembly 3 and the filter assembly 2. Figure 3 The partial structure of the discharge assembly 3 when it is in the open state is shown. When the sealing plate 33 moves from the closed position to the discharge position, a region for material to pass through is formed below the feed port 23, allowing the material in the housing 21 to enter the discharge assembly 3 downward through the feed port 23.

[0025] A closing element 31 is provided on one side of the discharge assembly 3. The closing element 31 is connected to the sealing disc 33 and is used to drive the sealing disc 33 to move along the guide groove 32. Figure 3 As shown, the opening and closing component 31 includes a threaded post 311 and a limiting disk 312 disposed at the end of the threaded post 311. The threaded post 311 is threadedly engaged with the discharge assembly 3, and the limiting disk 312 is rotatably connected to the sealing disk 33.

[0026] When the opening / closing element 31 rotates the threaded column 311, the threaded column 311 moves axially relative to the discharge assembly 3 due to the threaded engagement between the threaded column 311 and the discharge assembly 3. This axial movement of the threaded column 311 is transmitted to the sealing plate 33 via the limiting plate 312. Since the limiting plate 312 is rotatably connected to the sealing plate 33, the limiting plate 312 can rotate relative to the sealing plate 33 when the threaded column 311 rotates. This prevents the rotation of the threaded column 311 from directly causing the sealing plate 33 to rotate; instead, the limiting plate 312 pushes or pulls the sealing plate 33, causing it to move linearly under the constraint of the guide groove 32.

[0027] By changing the rotation direction of the opening and closing element 31, the axial movement direction of the threaded column 311 can be changed, and the limiting plate 312 can push or pull the sealing plate 33 accordingly, thereby realizing the reciprocating switching of the sealing plate 33 between the closed position and the discharge position.

[0028] like Figure 2 and Figure 3 As shown, the discharge assembly 3 is also equipped with a flexible scraper 5, which is disposed on the moving path of the sealing disc 33. The scraping end of the flexible scraper 5 is in elastic contact with the surface of the sealing disc 33 facing the feed inlet 23, so that when the sealing disc 33 moves along the guide groove 32, its surface can slide relative to the flexible scraper 5.

[0029] When the sealing disc 33 moves from the closed position to the discharge position, the side of the sealing disc 33 facing the feed inlet 23 is scraped by the flexible scraper 5. The scraping end of the flexible scraper 5 scrapes relative to the surface of the sealing disc 33 in an elastic contact state, which can scrape off the powder particles and residues attached to the surface of the sealing disc 33. When the sealing disc 33 moves from the discharge position back to the closed position, the sealing disc 33 is scraped by the flexible scraper 5 again, and the flexible scraper 5 scrapes the corresponding surface of the sealing disc 33 again.

[0030] Therefore, the flexible scraper 5 does not require a separate cleaning motion. The reciprocating movement of the sealing disc 33 itself to open and close the feed inlet 23 simultaneously constitutes the relative motion required for the flexible scraper 5 to clean the surface of the sealing disc 33. Each time the sealing disc 33 performs an opening or closing action, it is scraped by the flexible scraper 5, thereby reducing the continuous adhesion and accumulation of powder particles on the surface of the sealing disc 33.

[0031] The discharge assembly 3 is also equipped with a sealing ring 6. For example... Figure 2 and Figure 3As shown, the sealing ring 6 is positioned corresponding to the feed inlet 23 and is located at the sealing engagement position of the sealing disc 33. When the sealing disc 33 moves along the guide groove 32 to the closed position, the sealing disc 33 fits against the sealing ring 6, forming a sealing fit between the sealing disc 33 and the feed inlet 23. When the sealing disc 33 moves towards the discharge position, the sealing disc 33 gradually avoids the sealing ring 6 and the feed inlet 23, causing the feed inlet 23 to switch from a closed state to a state connected to the discharge channel.

[0032] Because the flexible scraper 5 scrapes the surface of the sealing disc 33 facing the feed inlet 23, it can reduce the amount of powder particles adhering to the surface as the sealing disc 33 moves back to the closed position. When the sealing disc 33 re-mates with the sealing ring 6, it can reduce the possibility of adhering particles entering the mating area between the sealing disc 33 and the sealing ring 6, thereby reducing the impact of powder residue on the sealing mating.

[0033] like Figure 1 and Figure 2 As shown, the discharge assembly 3 is detachably connected to the filter assembly 2 via fastener 4, which is located at the connection point between the filter assembly 2 and the discharge assembly 3. During normal operation, the fastener 4 keeps the discharge assembly 3 mounted at the bottom of the filter assembly 2, ensuring that the discharge assembly 3 and the feed inlet 23 are in the correct assembly positions.

[0034] The flexible scraper 5 primarily utilizes the reciprocating movement generated during the daily opening and closing of the sealing disc 33 to scrape its surface. After prolonged use of the adsorption reactor, if further cleaning, inspection, or maintenance of the discharge assembly 3 is required, the fasteners 4 can be removed, allowing the discharge assembly 3 to be detached from the bottom of the filter assembly 2. Removing the discharge assembly 3 facilitates cleaning and inspection of the areas containing the sealing disc 33, guide groove 32, flexible scraper 5, and sealing ring 6.

[0035] In actual operation, the sealing disc 33 is first positioned in a closed state. At this time, the sealing disc 33 is located below the feed inlet 23 and is in contact with the sealing ring 6, and the feed inlet 23 is in a closed state. The motor 1 drives the stirring component 22 to rotate inside the shell 21 to process the material inside the shell 21.

[0036] When material processing is complete and discharge is required, the opening / closing element 31 is rotated. The threaded post 311 in the opening / closing element 31 moves axially relative to the discharge assembly 3, and pulls the sealing plate 33 along the guide groove 32 from the closed position to the discharge position via the limiting plate 312. As the sealing plate 33 moves outward, it gradually avoids the material inlet 23, and at the same time, the side of the sealing plate 33 facing the material inlet 23 is scraped by the flexible scraper 5.

[0037] When the sealing plate 33 moves to the discharge position, the sealing plate 33 avoids the material inlet 23. The material inlet 23 is connected to the discharge channel of the discharge assembly 3. The material inside the shell 21 enters the discharge assembly 3 through the material inlet 23 and is discharged downward. Figure 3 The diagram shows the structural state of the material discharge component 3 when it is in operation.

[0038] After material discharge is completed, the opening and closing element 31 is operated in reverse, causing the threaded column 311 to move axially in the opposite direction. This, in turn, pushes the sealing disc 33 along the guide groove 32 towards the feed inlet 23 via the limiting disc 312. During its return process, the sealing disc 33 passes by the flexible scraper 5 again, which scrapes the surface of the sealing disc 33 facing the feed inlet 23. After the sealing disc 33 continues to move to the closed position, it re-adheres with the sealing ring 6, thereby closing the feed inlet 23.

[0039] Therefore, this utility model utilizes the reciprocating movement that the sealing disc 33 needs to undergo during normal material discharge opening and closing to simultaneously complete surface scraping when the sealing disc 33 passes the flexible scraper 5, achieving daily cleaning of the material discharge sealing part without setting up a separate cleaning drive action; at the same time, the material discharge component 3 and the filter component 2 are connected by a detachable connection formed by fasteners 4, and after long-term use, the material discharge component 3 can be removed for further cleaning and maintenance of the internal structure, thus forming a structure that combines daily scraping cleaning with disassembly and maintenance.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
